14 Claims. (Cl. 20-42) This invention relates to windows and moreparticularly relates to awning type windows having improved lockingdevices.

Awning type windows,that is windows which pivot about a horizontal andgenerally vertically shifting axis, have long been popular for the highdegree of ventilation and illumination which they provide and for thegenerally airy decor which they lend to a room or porch. Most suchwindows comprise a plurality of windows in a single window frame, with acommon operator for all windows. Numerous different operating andlocking arrangements have been used and, while the window crank operatornormally controls all of the windows in a single frame, the lowermost orthe uppermost window is frequently moved differently than the otherwindows in order to provide proper locking and sealing. Operating andlocking arrangements thus have become quite complex and, even in thoseinstances where the windows are made of wood, have become quite costly.This increasing complexity has led to a certain amount of equipmentfailure and this in itself has militated against a more widespread useof such windows. 7

It is accordingly a primary object of the present invention to provideawning type windows which utilize a simple operating and lockingarrangement and which are relatively economical to produce.

It is another object of the invention to provide an improved awning typewindow which is simple and rugged in construction and durable in use.

It is another object of the invention to provide an improved awning typewindow having an improved closing and locking device associatedtherewith. I

It is a still further object of the present invention to provide animproved locking device for awning type windows.

These and further objects and advantages of the invention will becomemore apparent upon reference to the following specification and claimsand appended drawings, wherein:

"ice

Figure 10 is a vertical cross section of the lock taken on the line 1010of Figure 9;

Figure 11 is a further vertical cross section of the lock taken alongthe line 11--11 of Figure 9; and

Figure 12 is a plan view, partially in section, showing the top of theglass frame.

Referring to Figure 1 in the drawing there is shown generally at 10 awindow consisting of a frame 12 and window sash 14. The window frame 12consists of a pair of horizontal frame members 16 and 18 which aredadoed at the ends to receive vertical frame members 20 and 22. Thewindow sash 14 comprises a glass frame consisting of a pair ofhorizontal frame members 24 and 26 and vertical frame members 28 and 30in which a pane of glass 32 is mounted.

Referring to Figures 2 and 3, a pair of vertical strips 34 and 36 aremounted on the insides of vertical window frame members 20 and 22. Thesevertical strips 34 and 36 are possessed of an L-shaped cross sectionhaving smaller portions 38 and 40 and larger portions 42 and 44.Thelarger portions 42 and 44 are joined at their extremities byhorizontal strips 46 which extend across the bottom and top of thewindow frame on the inside of horizontal members 16 and 18, as is bestseen in Figures 3 and 4. The surface 40 of the vertical strips 34 and 36and horizontal strips 46 form the face which the glass frame rests upon,and the large portions 42 and 44 of the vertical strips 34 and 36 areprovided with sealing strips 50 and 52, as can be seen in Figure 2.These strips may be of any suitable type and are preferably of theneoprene or rubber variety having a tubular portion 54 and thin portions56 which are received in slots in the vertical strips. Similar sealingstrips are mounted on the back sides of the horizontal members 24 and 26in the frame for the pane of glass 32 and these horizontal sealingstrips cross the vertical sealing strips 50 and 52 to completely sealthe window sash when it is in a closed position. I

The frame for the pane of glass 32 is supported within the window frame12 by a pair of rollers 58 mounted on either end of the glass frame, asis best seen in Figures 5 and 12. Referring to those figures, it will beseen that the roller 58 is pivotally mounted upon a bracket 60 which issuitably screwed to the vertical member 28 and horizontal member 24which are offset at 61. This olfset does not interfere with the airtightness of the window since the window is sealed by sealing stripsinboard of the offset portions. This bracket 60 may also be seen in.Figures 3 and 4 wherein the frame for the pane of glass appears indotted lines. The rollers 58 are received in channels 62 for verticalmovement therein. The channels 62 are secured to the insides of thevertical members 20 and 22 in the window frame as by means of screws 64and 66 as is best seen in Figure 3. The bottom screw 66 is provided witha projecting head, as shown in Figure -2, to serve as a stop to limitdownward movement of the rollers 58. As can be seen in Figure 5, rollers58' are located above the top of horizontal members 24 in the glassframe and the horizontal member 16 in the window frame is recessed at 68to receive the rollers when the window is in a closed position.

Pivotally attached to the brackets 60 are a pair of actuator bars 70 and72 associated with the operator 74 and lock-76 respectively, as is bestseen in Figure 2. The actuator bars 70 and 72 are pivoted at 73 to thebrackets 60 and at the other ends within the operator 74 and lock 76respectively. The operator 74 is of a conventional sector and worm typeand causes rotation of the actuator bar 70 upon rotation of the crank78. As is well known with this type of window, this causes the glassframe to pivot about the rollers 58 while the rollers move vertically inthe channels 62 to open and close the window. Referring to Figure 3, thewindow sash is shown in a partially opened condition, whereas in Figure4 the window sash is shown in a closed position. The maximum openposition is limited by the engagement of the roller 58 with thelowermost screw 66 in the channel 62, as is best seen in Figure 3.

While the principle of operation of this type of awning window has beenknown for some time, it will be apparent from the foregoing that theconstruction and hardware for operating this particular window isextremely simple and inexpensive. Each window sash is assembled as aseparate unit and where it is desired to utilize a plurality of thesewindow sashes one above the other, individual window sash units arestacked but are still opened and closed by their individual operators.This provides a high degree of flexibility for the designer and permitsa widespread use of such awning windows, since the cost of the windowscan be kept at a reasonable level. While the windows may be made of anymaterials wood is preferred.

Referring toFigures 6 through 11, there are shown details of the lock ofmy window. This lock consists of a casing 80 having one vertical edge 82and a rounded edge 84. The casing has an outer wall 86 and an inner wall88. A skirt 96 projects from the outer surface of the inner wall and theedge of this skirt engages the inner surface of vertical member 22 inthe window frame when the lock is mounted as shown in Figure 2. Theskirt comprises a vertical portion 92, shown in Figure 9, a horizontalportion 93, a rising portion 94, an arcuate portion 96, and a straightportion 98. Attached to the ends of the casing are a pair of mountingfeet 100 and 102 which receive mounting screws 1G4 and 106, as is bestseen in Figure 8.

Referring to Figures 8 and 11, a pivot pin 108 is mounted in an aperturein outer wall 86 and it is received in a bushing 110 in inner wall 88.The outer wall 86 is thickened at 122 -at the point Where the pivot pin108 passes therethrough. Upon the pivot pin 108 there is mounted alocking plate 112 which is attached to the actuator bar 72. The lockingplate 112 is generally sector shaped and is provided with a pair ofconverging edges 114 and 116, a generally arcuate end 118 and a lockinglug 120. When the lock is mounted on vertical strip 36 the locking plateextends through a slot 109 therein.

Cooperating with the locking lug 120 is a locking cam 124 having areduced diameter stud 126 at one end thereof. The stud 126 is receivedin an aperture in a thickened wall portion 128 on outer wall 86 and theother end of the cam is provided with an additional stud 129 attached toan operating lever 130 extending upwardly past inner wall 88. A suitablehandle 132 may be provided on the lever 130. Referring to Figure 8, thecam 124 is cut away at 134. When the cam is in the position shown inFigure 8 the locking lug 120 engages the came 124 so that rotation oflocking plate 112 or movement of actuator arm 72 is impossible. Thus inthis position the window is locked. If the cam 124 is rotated until thecutaway surface 134 is in the position of the broken lines shown at 136,the locking lug 129 then clears the cam so that the window is unlockedand locking plate 112 and actuator arm 72 are free to move.

In closing the window, when the cam 124 is in the position shown by thebroken line 136 and when the locking plate 112 is in the position shownby the broken line 138, rotation of the cam 124 in a counterclockwisedirection positively cams the locking plate 112 into the position shownby the solid lines in Figure 8, wherein the window is completely locked.This. positive camming action permits tight sealing of the window andassists the operator in closing the window. This is important since theposition of the actuator arm of the operator during the last few degreesof closing is such that it is ditficult to exert adequate force toobtain a tight seal. The lock shown in Figures 6 through 11 thus notonly serves its function as a secure lock for the window, but also aidsin closing and Sealing the window.

Referring to Figures 2 and it will be seen that when the lock is mountedin position on a window there are no pivot pins extending outwardlytherefrom so that they might be bent and the unit damaged. Thus thepivot pin 124 on which lock operating lever 130 is mounted 7 iscompletely concealed. The arm 130 further extends out from the lockadjacent vertical member 22 so that it is absolutely impossible to bendthe lever in such a manner as to damage the pivot pin. Movement of thelever is limited by horizontal position 93 and rising position 94 ofskirt 90, as may be seen in Figure 9.

The window and lock of this invention are quite simple in construction,low in cost, and relatively easy to assemble. The lock is rugged anddiflicult to damage and serves the dual function of locking the windowand moving it into a position for locking.

The invention may be embodied in other specific forms without departingfrom the spirit or essential characteristics thereof. The presentembodiment is therefore to be considered in all respects as illustrativeand not restrictive, the scope of the invention being indicated by theappended claims rather than by the foregoing description, and allchanges which come within the meaning and range of equivalency of theclaims are therefore intended to be embraced therein.
